***Below I?m asking about possible during an emergency, not necessarily legal***
In planning my G3X Panel for light IFR, I?ve arrived at the point of choosing an IFR Navigator, Com and Nav Suite. My primary method of Nav will be WAAS GPS from the GTN650. My only concern is that if the box fails, I?ll also lose my backup approach capability through the integrated Nav Radio.
I can split the two up via a GTN625, and a GNC255, but then it occurred to me that the G3X has a built in WAAS GPS. If I ditched the Nav radio completely, and lost my GTN in IFR conditions, is it possible (not necessarily legal) to load an approach into the G3X and get on deck with its built in WAAS GPS? That could save $5000 off my avionics cost. It also aligns my play airplane with my work airplane in that they would both be IFR capable with very little redundancy.
I understand it wouldn?t be a legal, but if it is a viable way to get safe on deck during an emergency I would feel okay forgoing the added weight, cost and complexity of a Nav radio.
As I understand it, a radio stack with just a G3X, GTN625, single Comm Radio and G5 would be legal for IFR since no backup for WAAS is required by the FAR?s, and if it I had to use the E word I could realistically get on deck with the G3X.
Is my thinking way off base?
